焚烧处理黄姜皂素水解废液中试研究

Incineration for Treating Yam Diosgenin Hydrolysis Liquid Waste

针对黄姜皂素水解废液高有机物浓度、高含盐量的特点,采用焚烧法处理水解废液。结果表明,焚烧后废液中的有机物转化成无害的二氧化碳和水,完全杜绝了其对水环境的污染;焚烧产生的废气经处理后,颗粒物、SO_2和NO_x的平均浓度分别为27.4、68.5和159.7 mg/m3,可达到《锅炉大气污染物排放标准》(GB 13271—2014)的要求;焚烧后残渣主要含有无水钠镁钒和无水芒硝两种矿物。

According to the characteristics of diosgenin hydrolysis liquid waste, the incineration high organic concentration and high salinity of yam was adopted to treat the liquid waste. The results showed that organic matter in the liquid waste was converted to carbon dioxide and water after incinera- tion, and the pollution to water environment was eliminated completely. After treatment of waste gas pro- duced by incineration, the average concentrations of PM, SO2 and NO, were 27.4 mg/m^3, 68.5 mg/m^3 and 159.7 mg/m^3, respectively, which could meet the Emission Standard of Air Pollutants for Boiler （GB 13271 -2014）. The residue after incineration mainly contained vanthoffite and thenardite.
